American Staffordshire Terrier

Canis lupus familiaris

American Staffordshire Terriers, often shortened to am staff or amstaff, are a stocky, athletic AKC breed that shares its nineteenth-century English working roots with the American Pit Bull Terrier; the two breeds parted ways in 1936 when the AKC opened the studbook to a strain of the original line.
